Diagnosis. This is the smallest Bornean Amata. In facies it is not
dissimilar to A. pleurosticta Hampson but has all wing markings more
elongate, with the black separating them narrower. The posterior distal
transparent patch is divided by vein M3; sometimes the anterior patch also
extends to beyond vein R5. Each abdominal segment is ringed finely and evenly
with yellow. The male genitalia are distinctive.

Taxonomic notes. Bornean material referable to sala shows no genitalic differences
from typical Javanese huebneri, though the transparent patches on the
hind-wing and at the base of the forewing are somewhat larger.

Geographical range. Indo-Australian tropics to N. Australia.

Habitat preference. The specimen illustrated is from the lowlands of
Sarawak near Kuching; the series of sala is from Kinabalu, but no
altitude or habitat details were recorded.

Biology. The larva has been found feeding on rice in Java (CIE records).
